Busybox needed for many programs and ADB
I just gave a time-tested method
Download my version and see it.

I know very well about busybox, where it needs, whether to include and how.
Thank you but I need not to look to your works.
You can surely fetch some viewership to your thread if you needs by posting it here as you have made it for certain device.
For note2 int (n7100) there is already good work by as i9000 and mentioned in OP.

Busybox is The Swiss Army Knife of Embedded Linux
Busybox is set of programs which allow users to have Unix/Linux utilities in single small executable file, busybox multi-platform and it is made for linux based operating systems.
Busybox allows you or programs to perform actions on your phone using Linux commands. Android is basically a Linux OS with a Java compatible (Dalvik) machine for running programs. The Android kernel is a modified version of the Linux kernel. Busybox gives functionality to some application to work it.
In normal use few applications needs it separately, some applications like titanium backup itself having it's own busybox.
I recommend to install busybox only if your any application demand for that.
You can simply install it from play store, but i don't recommend for that, as sometimes it mess up when you need to uninstall it.
I recommend to flash busybox just with CWM OR If you have stock recovery then just use mobile odin to flash busybox flashable zip
